I don't have many options. E-tuning obviously didn't work out well for me. Local dyno tuning is a massive improvement, for sure.

I just went home and found some 1000cc injectors from LJ. I think we can take another stab at dyno tuning this with LJ as these are the injectors he uses on his E85 builds. Thanks LJ!

your opinion doesnt really hold water. this is the 3rd or 4th tuner you have tried and you have yet to get a car that runs correctly

King Tut · 08-12-2013, 07:19 PM

I am on my 2nd tuner too.

My car is perfect

Before they were like -25

No problems whatsoever

Here's the old stock vs turbo map.

Nice dude!
Take me for a ride sometime!!!!!

I have seen odd graphs produced from people using dynapacks before but you really need to see what is going on at your 4k to 5k. It is ither pulling timing. Some odd boost fluctuations, or air fuels are jacked. As well your trims should be no were near that far off. By no means am I trying to bash anyone but your tune is far from complete. Please do not beat on it to much until you figure out what is going on.

Ross · 08-12-2013, 10:37 PM

Also what is your commanded cam timing in the 4k to 5k area?

I believe it's mostly the pig rich tip-in. I'm barely driving it at all, not my dd.

I'm going to try and find some time on their dynapack to let LJ do his magic with the 1000cc injectors.

it would be if anyone would bother to install them on a stock pump gas motor before going FI. I'll probably go that route (fuel pump and injectors on NA engine) before installing a charger next year just so i can nail down the injector scaling before adding boost into the mix.

It's good he is looking at the trims under all 3 conditions (port only, direct only, both), at least it sounds like he is. If you log the correct parameters you can easily tell which set of injectors needs to be tweaked.

If you guys get stuck feel free to hit me up..

At my second home (WORKS). We're going to swap the wastegate spring (red+green=15psi), swap to the 1000cc injectors LJ@FullBlown sent me, back to the stock MAP sensor, and do some remote dyno tuning with LJ. Hopefully there will be some good news this time

Ross · 08-16-2013, 02:41 PM

Why use the stock map sensor if you are going for more boost?

Were going for whichever fullblown prefers. I believe they use the stock MAP sensor for their E85 builds.
